In my library of purchased games, there's a version of the Anomaly 2 game installer for OS.X. However, the version for mac OS.X does not appear in the game page.

The game launches well, passing the introductory cinematic and accessing the menu, then the very first mission to discover the controls.

The game requires the use of the left and right mouse buttons. On a trackpad, the game is unable to detect a press on the right button when this is generated by clicking simultaneously on the trackpad and on the "option" key of the keyboard. However, if you have configured the trackpad settings to emulate the right button by pressing it with two fingers simultaneously, then the game will correctly detect the right button being pressed.

This comment is simply intended to warn other players that this problem exists in the Mac version, as well as its workaround.
